At our institute, we seek answers to fundamental questions in particle physics and astrophysics. We pursue this through work on world class national and international facilities, such as accelerators and telescopes. The Institute for Particle Physics and Astrophysics aims to continue its prominent role over a broad spectrum of research programs. Our experiments employ forefront technologies resulting from intensive R&D programs that often also lead to innovations (detectors and analysis software) and spin-offs (e.g. in medical physics or security).
